Working Theory

A popular alteration amongst performance enthusiasts is to remove, gut or hollow the catalytic converter or to install an aftermarket header, to free the horsepower of the vehicle. Nowadays, vehicles are fitted with two up to four exhaust air fuel sensors, at least one precat lambda sensor that controls the fuel management system, and at least one post that monitors catalytic converter function. When the aftermarket headers are installed or catalytic converters are eliminated, the result is a catalyst efficiency below threshold check engine light failure code indicating that the converter is missing or not working properly. The souped-up engine now produces a larger amount of exhaust gases than allowed. Obviously you do not want to drive your Proton Waja with a constant CEL, further your vehicle will not pass emissions inspection in many areas with an illuminated service light. The only solution is to install an Proton Waja O2 simulator wired up to the post lambda probe’s harness in order to mimic a properly functioning exhaust oxygen sensor. It provides the Electronic Control Module with mimic, fluctuating voltage signal and fools the ECU into thinking the emission is normal. This Proton Waja oxygen sensor simulator will allow you to run without cats and still keep the ECU warning light off.

When check the engine light is tripped, the engine runs in ECM Safe mode, which is tantamount to restricted horses and spoiled fuel mileage. This Heated Proton Waja O2 Sensor Simulator eliminates up- and downstream sensors as well, fulfilling the prerequisite of sensor type, thus you can get rid of suffering service light. Magnum Oxygen sensor simulator is available to all vehicles on which the emissions are monitored through a 1 up to 4-wire narrowband zirconia exhaust o2 sensors functioning in a 0 up to 1.0 Volt fluctuating voltage range. It also features a standalone adjustable heater simulator circuit. Feel free to contact our engineers prior to purchase if you are unsure about your Proton Waja's sensor type. Magnum Oxygen sensor simulator cures all lean mix and other lambda probe related engine management codes caused by heavy exhaust modifications. Dual exhaust with 2 aftercat exhaust gas oxygen sensors requires two O2 sensor simulators. Our digital O2 Sensor Simulator is adjustable, making you enable to adjust the A / F ratio within a certain range that is still accepted by the Electronic Engine Management. You can now completely eliminate the zirconia narrowband type exhaust air fuel sensor.

Note

front exhaust oxygen sensor has to work flawlessly. Slow signal of precat exhaust gas oxygen sensor may prevent the oxygen sensor emulator from working. Headers require both up- and downstream Oxygen sensor simulation. In case of a single exhaust air fuel sensor or dual pipe exhaust system fitted with 2 exhaust o2 sensors only, the oxygen sensor simulator connects into these oxygen sensors. Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Are you concerned that ECU Safe mode was tripped due to the exhaust modification made on your Proton Waja? Are you fed up with resetting the PCM repeatedly? Hurry up and install this oxygen sensor emulator on your Proton Waja. With minimum efforts you can sort out the ECM Safe mode all on your own, as long as you are mechanical and electrical minded. Conduct the installation and feel the crackle of output again beneath the hood.

Compatibility - Rule of thumb Don’t want to waste your time installing oxygen sensor bypass gadgets that will never rid you of the service engine soon light for good? Choose the reliable solution that will surely rectify your MIL light issue rite away. These O2 Sensor Simulators are made to prevent the service light from illuminating and to prevent an MIL code from triggering when the cat converter(s) are removed, gutted or hollowed. The Magnum Proton Waja Oxygen Sensor Simulator is carefully calibrated to mimic the signal from the air fuel sensor to keep it in the range the Electronic Control Unit is expecting to see.

How can I figure out my sensor is a zirconia type?

Zirconia type exhaust gas oxygen sensors have 1 to 4 wires. 1 to 3 wires indicate a zirconia narrowband exhaust air fuel sensor definitely. In the case of 4 wires, two of the wires have to be identical for heater, whilst the rest 2 wires have to be different for signal sender and signal ground. Always reference the sensor-side colors of the wires coming out off of sensor head. ECU-side colors may convert through the plugs.

How to find out if it's a narrowband or wideband?

Typically 1 to 4-wire oxygen sensors are narrowband. There are exceptions though. A narrowband oxygen sensor's signal is constantly fluctuating in a range of 0 to 1.0 Volts depending on oxygen content in the exhaust gas. Any oxygen sensor that produces higher voltages, is determined to be a wideband oxygen sensor. Keep in mind, although a 4-wire O2 sensor can be wideband too, in common sense only 5 or 6-wire sensors are called wideband. If your O2 sensor has more than 4-wires, oxygen sensor simulator is not applicable.

Which sensor has to be tricked?

In general: the downstream but upstream has to work flawless in full range. If you intend to buy a simulator hence decatting, header or modified exhaust, the downstream sensor has to be fooled by all means. See position diagram Headers or precat gutting requires upstream simulator as well.

Questions and answers

Can I be positive this chip fixes my CEL issue for good and all?

Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor related codes will be gone. Upstream sensor if any has to be in good condition though. Please see prerequisites pertaining to sensor type and quantity of simulators.

What if I simply eliminate factory oxygen sensor?

Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code.

Why is it so important to cancel the trouble code?

While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively.

Do I need to buy this heated simulator or I can stick with cheaper EZ CEL Fix?

If you can use the heater of the factory oxygen sensor(s), you may wire up #795 EZ CEL Fix. This heated simulator #661 allows you to remove or eliminate the stock oxygen sensor completely.

What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems?

The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII vehicles made after 1996. They often don't work even on early fuel injected cars. If your vehicle had been manufactured after 1996 or you drive an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust.

Can I rally my two harnesses into one simulator?

No, simulators can't be spliced. Get rid of oxygen sensor related CEL issue yet today. Flat catalytic converter gutting or plain-tube decats will spoil low- and mid-end torque hence ruined engine flush due to inadequate exhaust back pressure and higher block temperature thus valves, cylinder head and other engine parts are constantly being exposed to undesired extra heat. True enough, maximum horsepower increases it still pertains to a higher RPM which perishes dynamic kick out acceleration throughout the RPM range, mostly on automatic vehicles, therefore to save money on fuel and enhance low and mid-end torque, highly recommended to install a reliable Decat . Plain decatting is judged unprofessional among serious tuners and enthusiasts. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when decatting or modifying an exhaust.

codes have been cleared

I had a lil trouble wiring up the sims to the factory harness there is a dust cover that had to be split but after that everything went right on. The codes have been cleared and surprisingly I noticed that throttle response was much improved. The power boost is also notable making the Charger really fun to drive. I think that I will get better gas mileage if MIL is not turned on.

car runs better than ever

im totally novice to vehicle computer electronics so i used the watch and learn approach to understand the wiring insructions and hookup went through easy thanks a million for expert advise and im glad to say car runs better than ever

sims worked plug and play

I cant tell any derogatory remark on these sims. Got them in no time shipping was free of charge and install was a breeze. As opposed to some reviewers after hook up my sims worked plug and play with no tune. So far i am very satsfied, my Enclave runs and averages heaps better.

soars after wiring up the o2 emulators

My Jimmy with headers and (removed) catback soars after wiring up the o2 emulators, The only minus I've found so far they dont come with factory plug on the pigtail. I'd buy again if needed. Have it shipped by priority it still took 3 days to arrive.

I hooked up these o2 bypass tunes to my fifth avenue v8 and I can tell, no reservations, I would recommend this company to anyone. Tech support is undescribable sensational thay can square away any issue.

get rid of MIL light for good

Shipped super fast fairly well wrapped. Very easy to install. What it will do: it will get rid of MIL light for good and allows you to set richer mix which I am pleased about. MIL warns you when certain limit reached. What is does not do. I though it will change shift points but unnoticeable. Will not increase horsepower or fuel economy beyond the loss due to safe mode. What magnum can do: to keep up awesome tech support. So all the way it is worth the money with minor infirmities. I recommend this product.
